Gene and Shannon get invited to the premiere of the new Cirque du Soleil show "Viva Elvis" in Las Vegas the same weekend Nick is going to celebrate his 21st Birthday with his friends. When Nick's Birthday plans fall apart, Shannon comes to the rescue and takes Nick out on the town for a celebration he'll never forget. Meanwhile, back in Los Angeles, Sophie is in charge of picking up Nick's Birthday present and making sure it gets home safe and sound.

When Shannon loses a mini-golf game and a bet to Gene, the overconfident Demon volunteers to appear at a Charity Golf Tournament hosted by KISS Lead Guitarist Tommy Thayer. The only problem is that Gene has never played Golf and thinks his mini-golf skills will help him win a bet he's made with Doc.
